point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57 N. It’s important to realize that getting a negative force value means the charges attract. The direction of that attraction is determined

motion control are called drives and employ any of the prime movers such as diesel or petrol engines gas or steam engines hydraulic motors and electric motors for supplying mechanical energy for motion control. Drives employing electric motors are known as Electrical drives. Fig 1.1 Block diagram of an Electrical Drive The advancement in electric drive system is very much related to the development in the power semiconductor devices technology.

SACE Stage 2 Physics Electric Fields 1 Solution 1. (a) State Coulomb’s Law. Any two point charges have acting on them equal sized oppositely directed forces acting along the line joining their centres. The magnitude of these equal sized forces is directly proportional to the product of the charges and inversely proportional to the square of their distance apart. The forces are attractive for unlike charges and repulsive for like charges. [pic]. e.g.

Mini Case Study Can GE Remake Itself as a Digital Firm? General Electric (GE) is the world ’s largest diversified manufacturer. Fortune named GE "America ’s Most Admired Company" in 1998‚ 1999‚ and 2000. Jack Welch‚ GE ’s CEO and Chairman since 1981‚ is often cited as the most admired CEO in the United States. Headquartered in Fairfield‚ Connecticut‚ the company consists of 20 units‚ including Appliances‚ Broadcasting (NBC)‚ Capital‚ Medical Systems‚ and Transportation Systems. With the acquisition

to let people know when to enter and also to research and learn more about parallel and series circuits. Introduction I am going to design an electric circuit for a Doctor’s surgery. There are two types of circuit’s Parallel circuit‚ and Series circuit. First I am going to explain what a circuit is and what the differences they have are. An electric current is a flow of charge. The charges are given energy and made of flow using a cell or a battery. Charges can flow easily through connecting

74 CREATIVITY AND INNOVATION MANAGEMENT Case Study: Jack Welch’s Creative Revolutionary Transformation of General Electric and the Thermidorean Reaction (1981–2004) Pier A. Abetti This case study draws a parallel between the French Revolution and the GE ‘revolution’‚ according to three waves of transformation. We discuss the ‘hard’ effects on GE employees (strategy‚ structure‚ employment‚ rewards) and the ‘soft’ effects (culture‚ work climate‚ indoctrination). In parallel with the French

6. To make the circuit “cold”‚ what do you need to do? WHY? Turn the resistance up and the voltage down. It completely stops the flow of electrons through the battery. Which means the battery is not able to work because there is no electric current being created. 7. Describe the relationship between voltage and
